Appropriate cut-off value for follicle-stimulating hormone in azoospermia to predict spermatogenesis

Reproductive Biology and Endocrinology, 2010
Background This study was undertaken to determine the optimal cut-off value for FSH to predict the presence of spermatogenesis in patients with non-obstructive azoospermia.

The use of deidentified organ donor testes for research

Andrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

Proteomic biomarkers in seminal plasma as predictors of reproductive potential in azoospermic men

Frontiers in Endocrinology
IntroductionAzoospermia, characterized by an absence of sperm in the ejaculate, represents the most severe form of male infertility. While surgical sperm retrieval in obstructive azoospermia (OA) is successful in the majority of cases, patients with non ...

First application of three‐dimensional light sheet fluorescence microscopy to human testicular tumors: New perspectives in histopathology

Andrology, EarlyView.
Abstract Background Testicular tumors are among the most frequently diagnosed cancers in young men. The consequences of this diagnosis are orchiectomies, severely restricting fertility. For these young patients, a comprehensive diagnostics would be desirable, achieving a refined diagnosis and improved therapeutic patient stratification.

An update on sperm retrieval techniques for azoospermic males

Clinics, 2013
The use of non-ejaculated sperm coupled with intracytoplasmic sperm injection has become a globally established procedure for couples with azoospermic male partners who wish to have biological offspring. Surgical methods have been developed to retrieve spermatozoa from the epididymides and the testes of such patients.

Folding, misfolding, and regulation of intracellular traffic of G protein‐coupled receptors involved in the hypothalamic–pituitary–gonadal axis

Andrology, EarlyView.
Abstract Background G protein‐coupled receptors are a large and functionally diverse family of membrane receptors involved in a number of biological processes. Like other proteins, G protein‐coupled receptors need to be properly folded in order to traffic to the plasma membrane and interact with agonist.

Initial motility and vitality predict the semen quality after long‐term cryostorage, even in patients with restricted ejaculate parameters

Andrology, EarlyView.
Abstract Background Cryopreservation of human semen is the cornerstone for preserving male fertility before gonadotoxic therapy or in cases of high variability in semen parameters. This is particular crucial in cases of severe oligoasthenoteratozoospermia (OAT), where diminished sperm counts may compromise planned intracytoplasmic sperm injection (ICSI)

Effects on the reproductive system in domestic dowl (Gallus domesticus) after embryonic exposure to estrogenic substances [PDF]

, 2007
Environmental pollutants with estrogenic activity have a potential to disrupt oestrogen-dependent developmental processes. Thus, the aim of this thesis was to investigated how embryonic exposure to the estrogenic pollutants EE2 (17 alpha ...
